In dyeing skeins of material it has been the custom to suspend` the skeins on rods supported in the dyeing solution, and to cause upward currents through the solution to slightly displace the skeins on the rods, in order to satisfactorily dye that portion resting thereon. Y

A serious ditliculty encountered in such procedure is that substantially horizontal cross currents occur, whichcounteractthe lifting action, resulting in streaked portions in the skeins. Attempts to' avoid this have been made, using increased pressure to establishthe desired currents. Such methods were largelyunsuccessful,inasmuch as the currents of liquid so 'produced impinged violently on the walls of the container, resulting in agitation Vof the liquid and consequent streaking 4fof the treatedy material. Thus streaking of; one form or another has been dicult to avoid.

By my invention the above ditlculties have been avoided by arrangingaffreadily accessible overflow of largeiarea for the Yupwardly using liquid. 1n this manner/the tendency to produce eddy currents is avoided.

An object of my invention is'to arrange means by which to avoid the above enumerated dilliculties.

Another object is to arrangean overlow of llarge volume for the dyeing of a dyeing apparatus. Another object is to constructa new v and improved type of battle yfor the liquor of a dyeingA machine.

A still further object is toiprovide an overi. flow gutter or channel fora dyeing machine,

combined with anew type of baliie to properlyguide the flow of liquor to and `from the gutter. Other "objects will present themselves kin the" light of rthe'description and appended claims. y f

In the accompanying drawing: Fig. 1 is a plan view of a dye` vat made in accordance with my invention; i y

Fig.'2 isa longitudinal sectional view on the lineQJ-Q, Fig. 1; 1 i Fig. 3 isa' transverse sectional view onthe liiie 3,-L3,"Fig-. 1;- and w f' .-Fig. 4 is a transverse sectional view on the line 4.-4, Fig. 1.

The dyeing machine comprises a base member l on which is mounted side walls 2, 3, and end walls 4 and 5. Adjacent the side walls 2 and 3 and the end wall 5 is a trough or gutter 6, which as seen in Fig. 2 extends diagonally upward from left to right.

As will be seen from Figs. l, 2 and 4, the dyeing chamber is closed'by a false bottom 1fL having a plurality oit' perforations or slots 1b therein. Liquid channels 1c from the propelling chamber to the dyeing chamber are dened by spacing members 1d which are supportedby suitable means such as channel members 1e, shown in Figs. 2 and 4. By these means the dyeing liquid can be forced in a uniform manner through all portions* of the dyeing chamber.

The gutter or channel 6 may be formed in any suitable manner, one form of which as shown comprises laterally extending portions 7 secured to the adjacent walls by any desired means with wings 8 extending upwardly from 7. These `wings extend beyond the edges of wallsQ, 3 and 5.

A cover member 9 extends across the top of wall 4, and terminates at its inner end in a downwardly extending baffle 10. While the cover (9 extends across the full width of the apparatus, the baille 1() extends only across the dyeing chamber, designated at 11, and deiined'by base 1, walls l2, V3, 5 and bathe 10.

- Slightly inset from wall 12, similar to 10. The purpose'ot these-baffles will be developed later.v Suitable agitating means maybe employed. As shown, one or more horizontally extending propellers 13 may be secured to vertical shafts 14 journalled in openings 15 in cover 9. These propellers may operate within closely surrounding cylindricaljackets 16 which are conveniently supported as by closure member 17. i

' Although these propellers may be arranged horizontally if desired, itV is preferredto varrange themto force the liquid to traverse a substantially vertical. path. e The ,material tobe dyeolis suspended in 5 is another battle the central portion 11, any suitable frame for carrying the material being employed. The propellers are put into operation, the shafts being operated from any suitable power source (not shown) and the liquor is forced down underneath baille 10, past curvedv por.- tion 18 in the direction of the arrows of Fig. 2, and thence upwardly where it overflows the edges into the trough or gutter 6.

Instead of hitting the wall 5 and rebounding to establish the Aundesirable eddy currents, the liquor will travel upwardly through the passage between wall 5 and baffle 12with but little resistance being offered, andlifting the check valve 19, will flow into gutter 6. In thismanner an overflow outlet of large area A and volume is provided. The overflow will descend the trough 6 by gravity, and` will again. pass through the propeller housing. The liquors traveling upwardly will lift the skeins and'dye the material uniformly. The motion of the liquid is continuous and is not sufficiently rapid toagitate it.

- Upon reversal of the propeller action the dye will be forced back up the trough to overflow throughout itslength into chamber 11i. At this time the check valve 19 willremain seated, due to the pressure of the liquid, and the dye will-be efficiently directed into chamber 11.

As will be readily seen, this invention is susceptible to numerous modifications, and it is intended that it be limitedonly by the scope of the appended claims.

I claim:
